Thimble jellyfish

Linuche unguiculata
只是會痛不要碰會痛,但不會對你造成嚴重傷害。
水母和會螫人的海洋生物 會螫人的觸手吃:肉
對人的危險: 疼痛可能會非常痛,但幾乎從來不會很嚴重。

The thimble jellyfish is a tiny jellyfish with a flat top and straight sides, shaped a bit like a thimble. It lives in warm waters of the western Atlantic Ocean, including the Caribbean. It matters because it is the most common cause of seabather's eruption, an itchy skin rash that swimmers can get from its larvae.1

It is usually found in warm surface waters, where it forms swarms. It has also been found at depths down to about 5,000 m. Swimmers in the Caribbean, the Gulf of Mexico and Florida may meet its larvae in the water.1

牠吃什麼?
It feeds on plankton. It pulls a current of water past its outstretched tentacles by pulsing its bell. Its stinging cells immobilise small animals, and the tentacles pass them to the mouth on the underside of the bell.1

怎麼認出牠

  • Tiny bell with a flat top and straight sides1
  • Sixteen grooves on the sides of the bell1

會螫人的觸手

有東西碰到時,成千上萬個小小的刺細胞就會發射。

牠的毒液有什麼作用?

Its stinging cells, called nematocysts, can cause a skin reaction in people. The stings are not painful, but they can form an itchy rash.1

牠對人有多危險?

對人的危險: 疼痛可能會非常痛,但幾乎從來不會很嚴重。

It is the most common cause of seabather's eruption in the Caribbean and the Gulf of Mexico. The condition happens when a swimmer touches a cloud of larvae, which stick to clothing and hair. In Florida, most cases occur between March and August.1

如果牠螫人

  • 離開水裡,把觸手拿掉(戴手套或用布)。
  • 熱帶箱形水母:在螫傷處倒醋至少 30 秒,求救,並準備好做心肺復甦術(CPR)。藍瓶水母和大多數其他水母:用海水沖洗,再用熱水止痛。

一定要先打緊急電話(112、000、911)。這是一般急救指引,不是醫療建議。 急救基本知識

注意安全

  • 絕對不要碰、抓或捉弄野生動物,就算是很小的動物,就算牠看起來在睡覺或已經死了也一樣。
  • 給牠空間。如果遇到了,保持冷靜,慢慢往後退,讓牠自己離開。
  • 如果被牠螫了:保持冷靜,保持不動,打緊急電話(112、000、911)或趕快去醫院。記住牠的樣子,有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己,而且牠更想躲起來。 更多安全知識

小知識

1

Its larvae cause most cases of seabather's eruption, a rash that can appear after a swim.1

2

The larvae are killed when a swimmer leaves the water and bathes or dries off. This releases their under-developed stinging cells onto the skin.1

3

Swarms can cover a million square metres of sea surface.1

4

Its orangish-brown colour comes from symbiotic zooxanthellae, tiny algae that live inside its bell.1

5

Spadefish, sunfish, green sea turtles and sea slugs eat it.1

6

It swims by pulsing its bell and rotating as it moves.1
